It's easy to forget that electrical systems have evolved over the years. What's best now may not have been best at the time, or may have been more expensive.I thought that might be what they were getting at. Seems like it would be easier/cheaper just to have a main in there.

Was at a house in town last week raising a service mast. Went to panel to shut off main breaker before POCO reconnect and discovered there was none!! Any of you guys see this very often?? I'm changing out this panel on Tuesday.
do they make a 7 pole handle tie?No mains is a very common sight here in So Cali.
Remember that a lot of older panels were installed before the six throws rule.
Panels popular here with no mains include Zinsco, FPE, Pushmatic, some older C-H, Wadsworth, and Westinghouse.
For a resi panel I've always thought the six throws rule was kinda dumb anyways..even a full 24-space panel can be shut off in less than six throws if you use the edge of your hand to hit several breakers at once.
